Deconstructing Triboinformatics: A Conceptual Framework for the Intersection of Machine Learning and Tribology
(The American Society of Mechanical Engineers (ASME), 2026)Abstract. Tribology has traditionally functioned as an empirical discipline, heavily reliant on physical experimentation rather than unified first principles. To address the resulting epistemic bottlenecks, the paradigm ... -
Decoupling Hardness From Erosion Resistance in High-Entropy Alloys
(The American Society of Mechanical Engineers (ASME), 2026)Abstract. One important mechanism of component degradation in particle-rich environments is solid particle erosion. Due to their unique mechanical reactions and compositional complexity, high-entropy alloys (HEAs) have ... -
Research on Water-Lubricated Bearings in Ultra-Long Shafting Systems: Constraint Mechanisms, Lubrication State Optimization, and Flow-Field Solution Methods
(The American Society of Mechanical Engineers (ASME), 2026)Abstract. Water-lubricated bearings (WLBs) in ultra-long shafting systems (ULSS) operate under highly complex service conditions, with the coupling effects of external loads, shaft deformation, and harsh marine environments. ... -
Psycho-Tribology: A New Branch of Tribology Has Emerged
(The American Society of Mechanical Engineers (ASME), 2026)Abstract. Tribology is the science and engineering dealing with friction, wear, and lubrication, and it was practiced already in ancient times, but the term tribology was only coined in 1966 after the Greek word Tribos ... -
Application of the Ree-Eyring Model to Liquid Lubricants
(The American Society of Mechanical Engineers (ASME), 2026)Abstract. One of the many contributions of Professor Ward Winer to tribology was his insistence that constitutive equations for liquid lubricants have a basis in empirical fact. He was awarded the 1986 Tribology Gold Medal ... -
The Machine Learning–Based Prediction and Experimental Validation of the Friction Performance of Recycled Brake Materials
(The American Society of Mechanical Engineers (ASME), 2026)Abstract. The increasing emphasis on sustainability in the transportation sector has driven interest in friction brake materials containing high fractions of recycled constituents. However, designing such materials while ... -
Coupled Effect of Lubricant Fill Volume on Drag and Friction Torque of Dip-Lubricated Wet Clutches
(The American Society of Mechanical Engineers (ASME), 2026)Abstract. Multidisc wet clutches are widely used in automotive and industrial power-transmission systems, and their performance is strongly influenced by operating conditions and the lubricating oil. In particular, the ... -
The Barus–Roelands–Eyring Viscosity Artifice: A Catastrophe for Elastohydrodynamic Lubrication
(The American Society of Mechanical Engineers (ASME), 2026)Abstract. Ward Winer was a pioneer in the high-pressure rheology of liquid lubricants who championed the use of viscometers to understand the rheology of elastohydrodynamic lubrication (EHL). The classical approach to EHL ... -
Impact of Angular Misalignment on the Wear and Thermal Behavior of Polymer Gears: Experimental and Analytical Insights
(The American Society of Mechanical Engineers (ASME), 2026)Abstract. Polymer gears are increasingly implemented in lightweight, noise-critical transmission systems; however, their performance remains highly sensitive to geometric imperfections, particularly under dry-running ... -
Real-Time Railhead Friction Estimation Using Machine Learning: Development of an On-Board-Train Data Capture System
